Human urinary myiasis due to larvae of Telmatoscopus (Clogmia) Albipunctata in Morocco: A case report

Abstract

This is the first case of urinary myiasis in the Morocco region caused by Clogmia albipunctata . Also known as Telmatoscopus albipunctata , is a fly species in the Psychodidae family. These flies thrive in unsanitary environments like bathrooms and sewers. Transmission occurs when flies lay eggs on moist surfaces such as urogenital discharge. The larvae hatch and can traverse the urethra, entering the bladder. Clogmia albipunctata larvae and adults decompose organic matter and pose health risks as vectors of pathogens and allergens. In our case, larvae were discharged through urine by a 46-year-old female cleaner from a low socioeconomic background who presented with intermittent emission of worms in her urine. She had mild hypogastric tenderness and a history of lower urinary tract symptoms without fever. Initially misdiagnosed with cystitis, her symptoms persisted, leading to the discovery of small, mobile vermiform organisms in her urine. Living in fly-infested conditions, she had no recent travel or medical history. Urine analysis confirmed the presence of Clogmia albipunctata larvae, diagnosing urinary myiasis. Treated with ivermectin and hydration, her symptoms resolved within a week. A follow-up cystoscopy showed no larvae, confirming a complete cure.
